I have but there are a few things that you need to do.
Make sure that the kick lever and the thread on the clutch are not going to cause the nut to back off. They did make both clockwise and counter clockwise threaded cranks. I forget what one is preferred. Orrrr you need to put in a nut with a cotter pin so it won’t back out. I have some but then you need to drill a hole in the crank for the pin.
I have done it before so I could have a roller bearing top end instead of the brass bushing from the older models
